Abstract:

【Objective】To clarify the host range of tomato yellow leaf curl virus(TYLCV)and to offer a theoretical foundation for the prevention and control of TYLCV in Shaanxi Province.【Methods】158 samples of 11 crops and 283 samples of 32 common weeds from Dali County,Jingyang County,and Yangling Demonstration Area in Shaanxi Province were collected at different time points and tested for TYLCV by PCR.【Results】Cucumber,pepper,eggplant,cowpea and weed amaranth all carried TYLCV,were the intermediate host of TYLCV and important sources of infection. Sequence alignment results further confirmed that the pathogen on these crops was tomato yellow leaf curl virus.【Conclusion】TYLCV could infect cucumber,pepper,eggplant,cowpea and amaranth. These were the intermediate hosts of TYLCV.

Key words: Shaanxi Province, Tomato yellow leaf curl virus, Host range
